Rapid divergence of phenotype but not of genotype is theoretically possible, but given the genetic closeness of the sampled individuals (and this assumes that the extant Giant tortoises identified as D. arnoldi and D. hololissa really are remnants of the same populations as those given these names but based on old material), should they be recognised as species separate from D. dussumieri?

After Suomi, Lesch, and Higley had grouped the monkeys’ 5-HIAA levels according to their serotonin genotype (short/long or long/long, but not short/short, which was too rare to be of use), they also sorted the results by whether the monkeys had been raised by their mothers or as orphans with only same-aged peers.
